Split-screen in DIAdem SCRIPT

by Active Participant jtagg82 on ‎10-04-2013 06:32 AM

When working in DIAdem SCRIPT, it is often necessary to work on more than one file at once. The way this is implemented at the moment is with tabs:


script before.png


However, it can be quite tedious to switch back and forth between 2 scripts for things like copy/pasting, comparing code or simply editing code on 2 files concurrently.

My suggestion would be for a SCRIPT editor with split screen functionality, roughly like this:


script after.png


With many users working with widescreens today, this would better make use of screen real-estate.

In VIEW tab, when working with 2D-graphs some times it is useful to change the line width, the background color, the axis color, the line style... as in the REPORTER tab because for analyzing and studying the data before having the final data to report, the VIEW tab offers much more comfort. The Curve and Axis Definition in REPORT can replace the current 2D Axis System Display window:











box plot

Status: New

Hey everyone,

There should be an integrated feature in DIAdem to create Boxplots. You can already find the min Q1 median Q3 and max in the analysis portion. I have not been able to find a good way to make a boxplot in DIAdem, and it's a very clunky process in excell. I've had to use DIAdem to process data then export the interested channels to excel to make acutal boxplots, which still requires a lot of manipulation.

BoxPlot Data.PNG


To do this in excel you create a modified boxplot based on the difference in the five number summary. These numbers are put into a stacked boxplot, then the settings are played with to give the finalized look of a box plot.


The Differences plotted as a stacked bar plot looks like the following with borders on and the bottom and top sections made invisible with error bars to mark the min and max values


There should be a way to do a similar process, or even an automatic box plot creator in DIAdem.


Let me know what you think,




it would be helpful to have the following option in the View:

In case of moving the cursor through the 2D-Graph, I would like to have the table scrolling automatically the same way with highlightning the values of the cursors position. 


Kind regards

Add 'undo' for VIEW

Status: Under Consideration
by Member JuliaDawkins on ‎08-31-2010 01:11 PM

Having 'undo' in REPORT is great, and would be just as great in VIEW!  Removing and adding channels from a 2D axis would be my favorite use of an "undo" function. 

Saving a complete project

Status: Under Consideration
by Member Ludwig72 on ‎06-30-2011 12:19 AM

A typically Diadem workflow consists of at least two parts: Navigator and View or Navigator and Report. 

I always have to save and load every single file separately.


I wish I could have a button "Save Project" where all files of the actual project were saved in a single package and a similar "Open Project" Button.

The package can be a Zip-File that contains all the *.TDM, *.TDX; *.TDV, *.TDR and *.VBS files of the open project.

Status: Under Consideration
This is something that the DIAdem R&D team is looking into adding in a future release of DIAdem. While is sounds like an easy to implement feature, we also have to consider the Units catalog, any user commands that might have been created, settings in the DDD (DIAdem configuration file) and some other parameters that would have to be part of a project file. This is a larger project that is on the wishlist list for a future release of DIAdem. Otmar

It's very common you need to do a presentation with several information and if you can put a video playing a synchronized video, map, audio and data graphs, like DIAdem VIEW do, your presentation will be cause a excellent impression. To do this today you need a capture screen toll, If DIAdem have a native tool to do this it would be great.




DIAdem VIEW zoom improvements

by Active Participant jtagg82 on ‎10-04-2013 06:22 AM

I'd like to propose a few improvements to the zoom functionality in DIAdem VIEW that are sorely missing usability-wise:


  1. Vertical band zoom: This would allow one to zoom in on a specific part of the y axis without touching the x axis. We have the horizontal, why not vertical?
  2. Sticky zoom button: When I want to zoom in to a specific part of a graph in successive steps, I have to click on the zoom button each time. It would be great to be able to click on it once to activate the zoom tool and to be able to zoom several times. (Not sure what the best mechanism is, but maybe a click with modifier key? Ctrl+click on zoom button keeps it active?)
  3. Zoom stack with undo: Following on from point 2, when I zoom in in successive steps, it would be nice to be able to go back to the previous zoom level. Right now I can only do a generic zoom out or cancel all zooming. It could simply be an extra button in the zoom palette that goes back up one level in the zoom stack (like an undo. It could even be integrated into a more generic undo functionality if it ever comes about.)


I think that for points 2 and 3 there are several ways this could be done. I think the focus should be on usability. The user needs to be able to navigate the data as quickly and as efficiently as possible and the current zoom implementation is clearly impractical for many users.

Hello ALL,


there is only one manual scale to be set in a 2D graph in VIEW Panel. It would be a great idea if setting manual scales would allow you to set seperate scales for seperate plots on one graph.




Thanks, Piotr

Status: Completed

Hello Piotr,


The feature you requested has been realized in DIAdem 2014. Follow these steps to make use of it:


  • In a VIEW 2D chart in DIAdem 2014 choose "n Y-Axes [Linear]" for the Y-Axis type to display an individual axis for each curve.
  • Open the "Display..." dialog to access the parameters of the chart
  • In the dialog check the scaling item "Curve related" to display the additional "Scaling" column in the curve list
  • To define an individual scaling for a curve choose "Edit..." from its scaling drop down box. This opens a new dialog which allows you to define a number of named manual scalings. Press OK to confirm your definitions.
  • Each of these named scalings can now be selected for each of the curves in your chart. Selecting the same scaling for multiple curves results in them sharing the same y-axis




Automatic indentation

by Member Thomas77 on ‎01-26-2015 03:45 AM

Hello everybody,
My suggestion concern the SCRIPT tab. I think that it is necessary to implement a real automatic indentation function as you can find in most of Integrated Development Environment.
Indeed, when you write a VBS code, you have to structure your code manually while DIAdem could structure it automatically.
For instance, after an "if" and until "end if" DIAdem could insert a tabulation.



3D axis diplay on VIEW

by Active Participant e.ono on ‎07-27-2014 07:49 PM



I have a customer who would like to use 3D Axis systems on VIEW section.


This function is for Report section.

As you can see below.DIAdem_Report.png


He would like to realize this function on VIEW section as well.


I wish this function would be made for VIEW section as well.

Being able to create a report with different page sizes


At the worksheet parameters you can choose to use local page format, but you can only select the orientation (portrait or landscape). I Propose to add page size property when you select to use local page format, being able to indicate Height, Width or ratio.


different page size.png

Status: Declined

Dear mdelsol, sorry for declining this suggestion because of following reasons:

(1) On the monitor, you wouldn't have an advantage because of sheet-autoscaling to a maximum display size

(2) It could only be relevant on printers: Here you couldn't choose different paper sizes for an automized print job. You have to handle different print jobs, so hopefully you could also use different REPORT layouts for different sizes.

DIAdem Standard Deviation Weighting

Status: New
by Member Sam.Hoyle on ‎08-06-2015 05:21 AM

I have been doing some data analysis in DIAdem; I have been taking some statistics on some data - working out variance and standard deviation.  I asked NI Support team whether 'Population' or 'Sample' weighting is used, as it was not mentioned in the help file. I understand that by default Variance and Standard Deviation are calculated using the 'Sample' rather than 'Population' formula. My company uses Population to work out some of the key performance data of the products we make.  At the moment I don't see a way of selecting which formula to Descriptive statistics.PNGuse so a little drop down next to the checkboxes so I can pick the type would be great.  For now I'm going to have to develop some VBScript or start using excel to do my data analysis.  As a footnote to this idea - may I also illustrate that calculating standard deviation directly feeds into process capability (Cp and Cpk).  Sample weighting is a little less friendly than Population weighting, so unwitting process control engineers may be finding their processes a little more (I think!) capable than what they truly are.






Hiding curves in View

Status: Completed
by Member BRennhofer on ‎10-20-2011 02:58 AM

Is it possible to expand NI Diadem View to an option that allows hiding of curves without changing the properties of the graph or curve.


See example in the attachments.


Thanks a lot


Status: Completed
In DIAdem 2014, you could hide curves in VIEW/2D-Axis Systems with a checkbox in the configuration dialog and in the legend (without open a dialog).

The idea is to provide a "Channel concatenation" button in the default Analysis panel > Channel Functions.

After clicking this button, a dialog box should open, where the various Channels of different Channel Groups can be selected for the concatenation process. In the same dialog box, some options for the channel concatenation could be selected as well.

In this moment, some example scripts can be found in the discussion board for the concatenation of N Channels in M Groups. However, these scripts are quite cumbersome, not easy to customize, and providing too many optional features that are aiming to address shortcomings in the time or data channels to be concatenated.
It is a good practice, however, to correct first the issues in your Time and Data channels that prevent them of being concatenated properly.

The channel concatenation function would be a very useful feature, especially for engineers working with big datasets, that are increasingly recorded in contemporary data acquisition.
Typical examples of big datasets are vehicle CAN network data, recorded over an extended period of time (weeks, months).
Usually, these data are divided into multiple data files, which then need to be concatenated afterwards in order to cover a selected recording period, prior to further analysis of the data.

Dear wimdr, thanks for describing your usecase in your last abstract. We think we had solved this with DIAdem 2015 in the NAVIGATOR panel: You could append existing data in the data portal directly from files, if they have a similar structure. Please use the 'Open' dialog or the context menu. We think this is a better workflow than first load the data side-by-side into the data portal and then move it into existing channels. Please see the DIAdem-Help => Append data   for conditions and rules to use this new DIAdem feature.

Time Format precision in DIAdem

by Member cfoe on ‎09-09-2013 10:43 AM



I checked the DIAdem hepl and saw that the time value converted in text only allows 4 digits for the fraction of a second.

But how can you display datetime in text for more precise values.


For example, if i acquire on a real time target, analog inputs data at 1MHz, all samples are more precisely time stamped than the best text value that you can display.


It would be very convenient to display time stamp like that : 06/19/2013 15:37:50.12345678

instead of that : 06/19/2013 15:37:50.0005


Thanks  !

Best Regards


Rather than a channel that has a "fixed" value (numeric or string), this new "calculation channel" type would be a function of other channels.  Currently, if Channel3 = Channel1 + Channel2, and then I change the values for either Channel1 or Channel2, I have to re-execute the calculation


ChnCalculate("Ch(""Channel3"") = Ch(""Channel1"") + Ch(""Channel2"")")


Now, if there was a "calculation channel" where I could define Channel 3 as "Channel1 + Channel2", I wouldn't need to perform this re-execution! 


Another way to explain is to have a channel that works like Excel calculation cells.  The cell calculation stays the same, and when the input cells change, the result cell is automatically updated. 


I'm not sure if I explained this well, please ask for clarification if necessary. 

Currently the data type of group properties is automatically set, when two colums are used, one for "Name" and one for "Value". (see picture, right side)

I recommend to enable the possibility to manually set the data type for every individual entry, regardless which column is chosen for Name and/or Value.Bild1.png

Being able to draw a pie chart

As the title says, DIAdem should have the capability to draw simple pie charts in the report section.

Time shift data feature

Status: Completed
by Member Shawn_S. on ‎01-17-2012 03:00 PM

Lately there has been a need by many individuals to shift data for one reason or another.  Possibly the data was collected without using a trigger to synch everything or just collected with an inevitable delay.


Would R&D look into a function that could mark two points in a customer's data and then align/shift the data so a comparison may be done of one data set against another?

Feature is released with DIAdem 2015: Please use "Synchronize Data from Different Files" in panel ANALYSIS/Channel Functions
